UNITED STATES GEORGE E. LYNCH AND THOMAS J. GRIFFITH, OF DARLINGTON, INDIANA.

GRAlN-ME.TER.

SPECIFICATION forming part of Letters Patent No. 270,821, dated January 16, 1883.

Application filed May 31, 1881. Renewed October 5, 1882.

To all whom it may concern:

Be it known that we, GEORGE E. LYNCH and THOMAS J. GRIFFITH, citizens of the United States, of Darlington, in the county of Montgomery and State of Indiana, have invented a new and valuable Improvement in Grain Measurers and Registers; and we do hereby declare that the following is a full, clear, and exact description of the' construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a longitudinal sectional view of our-invention, and Fig. 2 is a side view thereof. Fig. 3 is a transverse section.

This invention relates to improvements in grain-measurers.

The invention consists in the construction hereinafter set forth;

In the annexed drawings, A is a box or frame consisting of two compartments, B, formed by the division 0, and open at top and bottom. Above the division 0 is placed the hopper D, opening into both compartments.

.Journaled above the division 0 is the shaft E,

above and opening outward.

having the transverse arms F F and vertical arms G. At the ends-the arms F are connected by the bars H, the journals h of which bear in holesf, in said arms, and said bars having the fingers h with eyes 7L2. On one arm F is a stop, f. Arranged above shaft E and held by arms G is a plate, I. K K are springs running from the end of this plate to fingers h.

Suspended from arms F are the buckets L, of a given capacity. The bottoms l of these buckets have a slant toward the side a of the box, and at the lower end the sides I of these buckets are provided with doors M, hinged Pivoted at the ends of the box A are the beams N, having an adjustable weight, 0, on the outer ends, and theinner ends, at, beveled oif below at n and'projecting in the path of bars H, a catch-plate, P, keeping the beams from swinging too far in.

(No model.)

Q is the registering device consisting of an intermeshing chain ofgear-wheels, R S T, having dials and pointers. The wheels R and S have each an enlarged tooth, so that one revolution of each of these wheels causes the next wheel in the train to move one tooth by the teeth interlocking.

0n the end of shaft E is a catch pawl, U, which is arranged to engage the teeth of wheel R and cause its rotation. The plate I is swung to one side, so that the hopper D shall lead to only one ofv the compartments B. This causes the bar H on that side to turn on its journals against the spring K, and, sliding up the bevel n, it rests on top of end a of beam N. At the same time the hinged doors M are held closed by the sideaofthe box A. The amount ofgrain which isto be the unit having been determined, the weights 0 are placed accordingly. Grain is poured in the hopper and falls in the upper bucket, L, and as soon as the proper amount is in the bucket swings down, bar H sliding 0d of end a, the empty bucket comes up into position, plate I cuts off the hopper from the first compartment and opens it to the other, and the catch-pawl U causes wheel R to turn one tooth. At the same time the hinge of door M coming below the edge of the side a, said door is opened by the pressure of the grain and the latter runs out. this being facilitated by the slant of the bottom.

\Ve claim- The combination ofswinging beams N, having the ends a beveled at n, and carrying the adjustable weights 0, buckets L, shaft E, arms F, turning bars II, and springs K, as set forth.

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.

GEORGE B. LYNCH THOMAS J. GRIFFITH.
